Rubber rotor pump common fault analysis

Guide: Rubber lobe pump often have a lot of problems in daily use, the most common is that they do not start properly, or are hot after work, so how do you deal with these failures when they occur?

lobe pump

1、Impossible to start

If the lobe pump fails to start, the first thing we need to do is to

The first thing we need to do is to check whether the power supply is powered, whether the power connector is securely connected, whether the switch is in tight contact, and whether there is a problem with the fuse and the three-phase power supply.

If there is a failure in these areas, it is easy to troubleshoot and fix the problem. The reason for this is that the pump is too tightly packed or the impeller is clogged with debris between the pump and the body. The way to fix this is to loosen the packing and unclog the pilot tank.

2, the pump is hot

Rubber lobe pump heat is also very often encountered, generally because: bearing damage; rolling bearing gap left too small; pump shaft bending position is not the same center; in the equipment used in the tape is too tight; lubricating oil is not added in time, or the quality of the selected lubricant is not good.

The way to eliminate rubber lobe pump heating is to replace the bearings; remove the back cover of the equipment and add shims between the bracket and the bearing housing to make the gap larger; check and adjust the concentric position of the pump shaft; loosen the tape if it is too tight; add clean lubricant to the equipment if it is short of oil.

Rubber lobe pump common failure analysis is introduced here, in the use of the above problems, then must be timely to solve.
